左フレーム２１は、金属製のパイプを曲げ加工して形成されるものであり、床面に接触する底部２９、座体１１を支持する支持部３１などを有する。この支持部３１は、前後方向に略水平に延びるように形成される。左フレーム２１の支持部３１には右フレーム２３側（内側）に延びる平板状の爪金３３（本発明における脚取付部の一例）が前後方向に間隔を空けた２箇所に形成されている。爪金３３には、ネジ３５が挿入可能な貫通孔３３ａが形成されている。 The left frame 21 is formed by bending a metal pipe, and includes a bottom portion 29 that contacts the floor surface, a support portion 31 that supports the seat body 11, and the like. The support portion 31 is formed to extend substantially horizontally in the front-rear direction. The support portion 31 of the left frame 21 is formed with two plate-like claws 33 ( an example of a leg attachment portion in the present invention) extending in the front-rear direction and extending in the right frame 23 side (inner side). A through hole 33 a into which the screw 35 can be inserted is formed in the claw plate 33.

リブ４３は、座体１１から延び出した先端が座体１１の主たる面と略平行である平面状となるように（即ち、着座面１１ａに沿った平面状となるように）形成されている。リブ４３には、座体１１の主たる面と交差する方向に開けられたネジ穴４５が、脚部材１５の６箇所の爪金３３の貫通孔３３ａと対応する位置に形成されている。左フレーム２１および右フレーム２３の爪金３３に対応するネジ穴４５の周囲には、ネジ穴４５を中心とした円周状に溝部４７が形成されており、その溝部４７によって、ネジ穴４５を取り囲む円柱状のネジ取付部４９がリブ４３におけるその周囲の部分と区切られる。 The rib 43 is formed so that the tip extending from the seat body 11 has a planar shape substantially parallel to the main surface of the seat body 11 (that is, a planar shape along the seating surface 11a) . . In the rib 43, screw holes 45 opened in a direction intersecting with the main surface of the seat body 11 are formed at positions corresponding to the through holes 33 a of the six claws 33 of the leg member 15. Around the screw hole 45 corresponding to the claw 33 of the left frame 21 and the right frame 23, a groove portion 47 is formed in a circumferential shape centering on the screw hole 45, and the screw hole 45 is formed by the groove portion 47. The surrounding cylindrical screw mounting portion 49 is separated from the peripheral portion of the rib 43.

図３は爪金３３およびネジ取付部４９の周辺の拡大斜視図であるが、理解を容易にするために、座体１１におけるネジ取付部４９とリブ４３以外の部分は透視した状態となっている。座体１１を脚部材１５に取り付ける際には、リブ４３を爪金３３に接触させた状態で爪金３３の下方向からネジ３５を貫通孔３３ａに挿入してネジ穴４５に螺合させ、リブ４３と爪金３３とを固定する。 FIG. 3 is an enlarged perspective view of the periphery of the claw 33 and the screw attachment portion 49. However, in order to facilitate understanding, portions other than the screw attachment portion 49 and the rib 43 in the seat body 11 are seen through. Yes. When the seat body 11 is attached to the leg member 15, the screw 35 is inserted into the through hole 33 a from below the claw 33 with the rib 43 in contact with the claw 33, and is screwed into the screw hole 45 . The rib 43 and the nail plate 33 are fixed .

図４（Ａ）に示すように、爪金３３には、溝部４７の部分を除き、リブ４３における溝部４７の周辺に位置する周辺部５１と、ネジ取付部４９と、が、先端面（座体１１から延び出した先の面）において当接している（図４（Ａ）における斜線領域にて接触している）。なお、リブ４３におけるネジ取付部４９と周辺部５１とが本発明における座体取付部の一例である。また、ネジ取付部４９の先端面が本発明における第１の領域の一例であり、周辺部５１の先端面が本発明における第２の領域の一例である。ネジ取付部４９の先端面と周辺部５１の先端面とは同一平面となる。 As shown in FIG. 4 (A), the claw 33 has a peripheral portion 51 positioned around the groove portion 47 in the rib 43 and a screw mounting portion 49 except for the groove portion 47, and a distal end surface (seat). (The front surface extending from the body 11) is in contact (in the hatched area in FIG. 4A). In addition, the screw attachment part 49 and the peripheral part 51 in the rib 43 are examples of the seat attachment part in this invention . Further, the tip surface of the screw attachment portion 49 is an example of the first region in the present invention, and the tip surface of the peripheral portion 51 is an example of the second region in the present invention. The distal end surface of the screw attachment portion 49 and the distal end surface of the peripheral portion 51 are on the same plane.

また、上記実施例においては、爪金３３は平板である構成を例示したが、図７に示すように、先端に縦板部３３ｂが形成されていても良い。縦板部３３ｂがリブ４３の側面と接触することで、リブ４３の歪みをより抑制することができる。なお、縦板部３３ｂが本発明における接触面の一例である。 Moreover, in the said Example, although the nail | claw metal 33 illustrated the structure which is a flat plate, as shown in FIG. 7, the vertical board part 33b may be formed in the front-end | tip. When the vertical plate portion 33 b is in contact with the side surface of the rib 43, the distortion of the rib 43 can be further suppressed. The vertical plate portion 33b is an example of a contact surface in the present invention.
